PrimeLoop and the Geothermal Cooling Revolution in Saudi Arabia Image: Pictorial Views Saudi Arabia is entering a new phase in cooling technology, and geothermal cooling is becoming one of the most compelling solutions in that transition. At the center of this shift is PrimeLoop, Strataphy’s proprietary geothermal cooling system, which is being positioned as a commercial answer to one of the region’s most urgent infrastructure challenges: how to cool buildings efficiently in extreme heat while reducing electricity demand and water use. This matters because cooling is not a minor utility in the Gulf. It is a core operating cost, a grid stability issue, and an environmental pressure point all at once. In a country where ambient temperatures can push conventional air-conditioning systems to their limits, the search for smarter cooling is no longer theoretical. It is now a commercial necessity. PrimeLoop is interesting because it does not simply improve on conventional cooling. It rethinks...

Why this partnership matters for the geothermal sector Geothermal heat offers a predictable, baseload source of low-carbon thermal energy that can decarbonise district heating, industry process heat and building heating demand. Scotl...

Eavor Secures Kleefeld II: A New Milestone for Hannover’s Deep Geothermal Ambitions Image: A Thematic image of The Eavor Project at Geretsried  Eavor’s new Kleefeld II permit marks an important step forward for deep geothermal development in Hannover, reinforcing the city’s position as one of Germany’s most closely watched urban heat-transition markets . The licence covers about 64.5 square kilometers, lasts for three years, and combines the former Buchholz and Kleefeld I exploration areas into a single, larger field that Eavor already controlled. The decision is more than an administrative update. It signals continued confidence in geothermal as a practical, scalable source of district heating in a dense metropolitan region. For Hannover, it also strengthens a project that has been building momentum for several years and could become a reference case for other European cities seeking cleaner, locally produced heat. A New Chapter For Hannover Kleefeld II sits in the northeast of...

The Disparity Between Anticipated and Actual Geothermal Steam Output Image: thematic image of the Hellisheiði geothermal power plant in Iceland  Geothermal energy is one of the most dependable baseload renewables, but the gap between expected steam output and real production remains a central industry problem. Exploration models are always incomplete, and once wells are onstream, pressure decline, scaling, corrosion, and thermal breakthrough steadily erode performance. Why Forecasts Miss the Mark Exploration depends on sparse wells, surface manifestations, geophysical surveys, and geochemical indicators, so it only samples a small part of a complex reservoir. Reservoirs are rarely uniform, and permeability, porosity, mineralogy, and thermal conductivity can vary sharply over short distances, which means early temperature or chemistry readings can overstate how much of the reservoir will actually support long-term production. Phase behavior adds another layer of uncertainty. In two-...

Texas Issues Second Deep Geopressured Geothermal Permit, What it Means for U.S. Geothermal Development The Texas Railroad Commission (RRC) issued its second permit for a deep geopressured geothermal well in July 2026, approving Quidnet Energy Deployment LLC to drill a geothermal energy storage well in Galveston County. This permit follows the RRC’s first deep geopressured authorization in February 2025 for Sage Geosystems in Atascosa County. Together, these approvals mark a meaningful step in Texas’s pivot from traditional fossil-fuel regulation toward enabling novel subsurface energy technologies, leveraging decades of oil and gas oversight to manage drilling, completion, and subsurface engineering risks. This article explains geopressured geothermal fundamentals, why Texas matters, technical and environmental considerations, market and policy implications, and what to watch next for developers and stakeholders. What is Deep Geopressured Geothermal? Deep geopressured geothermal syste...

XGS Energy Weighs IPO After Hiring Morgan Stanley, Chasing Fervo's Geothermal Momentum Geothermal developer XGS Energy has hired Morgan Stanley to evaluate an initial public offering, positioning itself as a potential second geothermal IPO of 2026 after Fervo Energy's blockbuster listing. The move underscores growing investor appetite for clean, firm power technologies as data-center demand and grid reliability concerns reshape the energy investment landscape. The Scoop: Morgan Stanley, IPO Timing, and Market Context In early July 2026, Axios Pro reported that XGS Energy engaged Morgan Stanley to assess a public listing, with company leadership potentially deciding within about a month whether to proceed. The timing is strategic: Fervo Energy's May 2026 IPO created a rare "open window" for geothermal equities, providing valuation benchmarks and investor education that earlier private rounds lacked. For investors, the narrative is straightforward. If Fervo proved t...

The Economics of 10 MW, 50 MW, and 100 MW Geothermal Plants Image: A thematic image of a geothermal power plant  Geothermal power has a simple promise and a complicated price tag. It turns heat from deep underground into steady electricity, but the money goes out long before the power comes in, because exploration, drilling, plant construction, and grid connection all happen up front. That is why plant size matters so much. In general, 10 MW projects tend to be the most expensive per kilowatt, 50 MW projects usually strike a better balance, and 100 MW plants can be the most efficient on a cost per electricity basis if the reservoir is strong enough. Why geothermal costs so much upfront The economics of geothermal are driven by risk and scale. A developer has to locate the resource, confirm temperature and flow, drill wells, build surface facilities, and connect everything to the grid before a single dollar of revenue is earned. That makes geothermal very different from technologies...

Kaishan , Halliburton Team Up on Advanced Geothermal, Green Fuel Projects Kaishan Group and Halliburton have deepened their cooperation with a strategic memorandum of understanding centered on advanced geothermal development, especially enhanced geothermal systems (EGS), along with green hydrogen and green ammonia opportunities. The deal builds on earlier Indonesia drilling work and signals a broader push to combine Halliburton’s high-end well-construction capabilities with Kaishan’s geothermal equipment and project-development platform. Partnership Background The relationship did not begin with the July 2026 memorandum. In February 2026, Halliburton said it had won a multiyear contract from KS Orka Renewables , part of Kaishan’s wider corporate group, to support geothermal well construction at the PT Sorik Marapi Geothermal Power and PT Sokoria Geothermal Indonesia projects in Indonesia. That work covered directional drilling, cementing, drilling fluids, and drill bits across several...

Who Is Financing the Next Generation of Geothermal Projects? Image : A thematic image of a geothermal power plant  The next generation of geothermal projects is being financed by a wide mix of venture capital firms, strategic corporate investors, commercial banks, institutional funds, and project finance lenders. The financing landscape is changing quickly because geothermal is moving from a niche clean-energy option into a serious infrastructure asset class with the potential to deliver reliable, 24/7 power at scale. Why geothermal finance is changing For years, geothermal struggled to attract large pools of capital because many projects were seen as technically risky, geographically limited, and difficult to scale. That perception is shifting as advanced geothermal technologies, especially enhanced geothermal systems, expand the number of places where geothermal can work. Investors now see a larger addressable market, stronger power demand, and better alignment with the needs of...

Geothermal EPC Companies: How Developers Choose a Contractor Image: A Thematic image of a geothermal power plant  Geothermal developers choose EPC contractors by combining technical geothermal experience, financial strength, execution credibility, and the ability to manage field-specific risk. In recent awards, the strongest bidders have been those with proven geothermal references, repeat-delivery history, and the ability to package engineering, procurement, construction, and commissioning into one bankable offer . Why geothermal EPC is different Geothermal EPC is more complex than standard power plant construction because the contractor must build around a live underground resource. That means the project team has to deal with reservoir uncertainty, steam chemistry, scaling, corrosion, reinjection behavior, plant-field interfaces, and grid interconnection all at once . For developers, this turns EPC selection into a risk-management decision. The contractor is not just a builder; ...
